At first glance, the X20 looks just like its predecessor (the X10), although it’s now available in a very pretty silver-and-black finish, alongside the conventional all-black. But inside it offers a couple of very significant differences. The first is a brand-new sensor, a 2/3″ type ‘X-Trans CMOS’ design that uses the same novel color filter array as Fujifilm’s recent APS-C cameras. This sensor also has phase detect autofocus built right into it – not new to Fuji cameras, but a change from the X10. The second big change is an updated ‘Advanced Optical Viewfinder’ that includes a detailed information overlay, showing key exposure data and focus confirmation.
